Application tiled September 21, 1927. Serial No. 220,994.

I v to provide novel and'efi'ective mechanism that will insure thesheets engaging and being directed along the guides, so that they willbe in proper position to be fed into the mecha nisrn that operates uponthem.

In the accompanying drawings Figure 1 is a plan view of a guide andportion'of the conveyer associated therewith and showing the novel sheetdirecting mechanism,

Figure 2 is a longitudinal sectional view .on

the line -2 2 of Figure 1,

Figure 3 is a cross sectional view on the line 3 3 of Figure 1, ,y

Figure 4 isa plan view of one of the directing rollers and theassociated ball thereon.

In the embodiment "disclosed, the guid for the sheets is preferably inthe form of an angle iron 5, having an upstanding guide flange 6 and ahorizontal fiange 7. The con-` veyer for the sheets is shown ascomprising endless tapes 7 Y passing around rollers 8, one of thesetapes 7a'having its upper or active stretch resting on the horizontalflange 7 of the guide.

It will be understood that the sheets are delivered successively on tothe tapes at the lefthand end'of the machine from a. feeder or othersuitable apparatus, and are discharged from the right-hand end. In orderthat the sheets may be properly positioned when delivered from theconveyer, they should be against the upstanding flange 6 of the guide.To accomplish this there are provided a plu.- rality of directingrollers 9, which are provided with rubber or other peripheral surfaces10 that will cause frictional engagement With the sheets. These rollersare carried by shafts 11 journaled in boxes 12 secured tothe .under sideof theguide 5 and having axes of /rotation inclined-to the guide andconveyer -tapes 7 il The outer ends of the shafts 11 are provided withpulleys 13, around which pass driving belts 14 operated from a pulley 15on `one ofthe conveyer rollers .8. By reference to Figure 3, it will benoted that the sheets, as A, carried by the conveyer tapes, are engagedby the rollers 9, which are arranged beneath their path of travel.

Secured to the upstanding flange 6 of the guide 5 is aretaining bar 16that overlies the horizontal flange 7 and the rollers 9. This bar isprovided with vertical openings or sockets 17 arranged over the rollers10. In

.the sockets are located bearing balls 18 that thus rest upon therollers and on the` sheets A as they pass over the same.

' By reason of this construction, it will bel evident that thev sheetsas theyy are carried by the conveyer tapes 7a-will pass between therollers 9 and the balls 18, the latter'serving to hold the sheets uponthe rollers and because of the inclinationof these rollers the sheetswill be moved until their edges strike against and travel alongy theoutstanding guide flange 6. s Y

From the foregoing, itlis thought that the construction, operation andmany advantages 0f the herein described invention .will be apparent to-those skilled in the art without further description, and it will beunderstood that various changes in the size, shape, proportion and minordetails of construction may be resorted to without departing from thespirit or sacrificing any of the advantages of the invention. Y

What I claim, is: t 4

1. In a structure of the character set forth, the combination with aguide for the sheets, of spaced conveyer tapes operating longitudinallyof the guide, one of said tapes being located directly adjacent to saidguide,a sheet engaging roller located between the tapes and having itsaxis of rotation at an inclination to the guide, a ball holder mountedon the guide and overhanging the adjacent tape and the space between thetapes, and a ball in the holderl restin on the sheets over the rollerand between t e tapes.

2.. In a structure of the character set forth, the combination with auide for the sheets comprising an angle bar aving a horizontalsupporting fiange and an upstanding guide said roller having its axis ofrotation disposed at an inclination to the guideange, a ball holder, anda ball inthe holder that rests onl the sheets above thevroller andalongside the 5 conveyer member.

3. In a structure of the character set forth, the combination with aguide for the sheets, comprisingV an angle bar having a horizontalsupporting ange and an upstanding guide flange, of spaced conveyertapes, one of which travels on the supporting Jlang, a sheet engag'ingroller located between'the tapes, said roller having its axis ofrotation disposed at an inclination to the guide flange, a bar securedto the upstanding flange of the guide and overhane'ing the tape on thehorizontal flange and the' adjacent space between the tapes, and afreely rotatable ball in the bar supported by the underlying roller.
